[0138] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0139] In some implementations, the PCell in the CA is responsible for receiving system broadcast information, paging, and Radio Resource Control (RRC) signaling connection management and mobility, while the system broadcast information on the SCell is configured through RRC-specific signaling, and the SCell is responsible for data transmission and reception.

[0140] In some implementations, the PCell and at most one SCell may have a Physical Uplink Control Channel (PUCCH) to enable HARQ feedback and channel state information (CSI) reporting for all carriers within the PUCCH group.

[0141] In some implementations, when configuring SCells: each SCell is associated with an index, and UL carrier configuration information can be nested when configuring DL carrier configuration information. When configuring a carrier-aggregated SCell, only DL carriers can be configured, or both DL and UL carriers can be configured simultaneously; therefore, the number of DL carriers is always greater than the number of UL carriers.

[0142] In some implementations, due to the diversification of services, some services require higher UL throughput than DL throughput, and carrier aggregation configurations cannot meet these diverse service needs. Furthermore, there is a one-to-one association between DL and UL carriers, such as a System Information Block 2 (SIB2) linkage. This lack of flexibility in carrier management makes it impossible to meet the high UL data throughput requirements of services.

[0143] In some implementations, during mobility operations, changes to a PCell trigger a cell handover process, even if the target cell is a SCell within the CA, due to the PCell's functional responsibilities. During handover, key changes lead to MAC resets, Packet Data Convergence Protocol (PDCP) or Radio Link Control (RLC) reconstruction, resulting in service interruptions and packet loss, impacting service performance. Furthermore, if a PCell experiences a Radio Link Failure (RLF), regardless of whether the SCell experiences an RLF, it will trigger a PCell RLF, thereby triggering RRC connection reconstruction, which also leads to service interruptions and packet loss, impacting service performance.

[0144] In some implementations, traditional mobile communication system designs, such as CA, still assume a scenario dominated by DL (Deep Flow) services. With the development of communication technologies, for example in future 6G networks, there are use cases with high UL (Ultra-Low Flow) traffic loads, including remote driving, machine vision, and factory video surveillance. In these use cases, DL data traffic is limited, while UL traffic will be much larger. In PCells, Time Division Duplexing (TDD) configurations are typically designed to support more DL time slots, which is not UL-friendly. Synchronization Signal Block-less Scells (SSB-less Scells) can be primarily used to support the additional UL traffic in such scenarios with high UL usage. DL services and Network (NW) signaling will be offloaded to PCells or other SCells. Since only UL traffic can be scheduled in SSB-less SCells, from an energy-saving perspective, the network can correspondingly shut down the transmitters in SSB-less SCells, thus anticipating significant network energy-saving gains.

[0145] In some implementations, a cell may have one DL carrier and two UL carriers, namely the Normal Uplink (NUL) and the Supplementary Uplink (SUL).

[0146] Introducing a SUL frequency can improve uplink coverage in the NR high-frequency band. Terminal uplink power is limited, and the NR spectrum has a relatively high frequency, resulting in high propagation loss, thus limiting uplink coverage. To improve uplink coverage, utilizing the LTE spectrum (relatively lower frequency) as the uplink SUL can enhance uplink coverage.

[0147] Among them, the two ULs and one DL belong to the same cell, and at most one Physical Uplink Shared channel (PUSCH) can be used for transmission at any given time.

[0148] Unless the network explicitly instructs the terminal to use either NUL or SUL, the terminal determines the UL selection based on a measurement threshold. This threshold is configured and broadcast in the system broadcast.

[0149] The two UL carriers can be dynamically switched, indicated by Downlink Control Information (DCI).

[0150] In this implementation, although a cell supports two UL carriers, the two UL carriers cannot transmit data simultaneously. The purpose of SUL is mainly to enhance UL coverage, but it cannot solve the problem of improving UL throughput. If multiple uplink carriers in a cell transmit uplinks simultaneously, it can effectively improve UL throughput. However, how to report PHR in this scenario is a problem. If PHR reporting is done at the per-cell level, it cannot reflect the PHR status of each carrier in a cell.

[0152] In step S2101, network device 102 sends configuration information to terminal 101.

[0153] In some embodiments, terminal 101 receives the configuration information.

[0154] In some embodiments, the configuration information includes the uplink transmit power corresponding to different uplink carriers. For example, in this embodiment, network device 102 configures the uplink transmit power for each uplink carrier.

[0155] Optionally, the uplink transmit power configured for each uplink carrier in the configuration information can be used by the terminal to determine the PH corresponding to that uplink carrier. Optionally, the corresponding uplink transmit power and PH can be reported in the PHR of that uplink carrier.

[0156] Optionally, the uplink transmit power configured for the uplink carrier in the configuration information can be compared with the maximum configured transmit power P determined by the terminal. CMAX Correspondingly.

[0157] In some embodiments, different uplink carriers include multiple uplink carriers of a cell.

[0158] In some embodiments, different uplink carriers include multiple uplink carriers of multiple cells, or in other words, different uplink carriers include at least one uplink carrier of each of the multiple cells.

[0159] Optionally, for multiple uplink carriers in a cell, the terminal can support simultaneous uplink transmission on multiple uplink carriers in that cell, or the terminal can support simultaneous uplink transmission on at least two of the multiple uplink carriers.

[0160] In some embodiments, configuration information can be sent via RRC signaling.

[0161] Optionally, configuration information can be sent via RRC dedicated signaling.

[0162] In step S2102, network device 102 sends instruction information to terminal 101.

[0163] Optionally, the indication information is used to indicate whether at least one uplink carrier is activated. Uplink carrier activation indicates that the uplink carrier can perform uplink transmission.

[0164] In some embodiments, network device 102 may indicate whether an uplink carrier is activated via a MAC CE. For example, network device 102 sends a MAC CE to terminal 101, the MAC CE including indication information.

[0165] In one example, the MAC CE carrying indication information may include:

[0166] A serving cell identifier (ID) is used to identify a serving cell.

[0167] The fourth bitmap corresponds to one uplink carrier among the multiple uplink carriers of the serving cell corresponding to the serving cell ID. If one or more bits in the fourth bitmap have the first value, it indicates that the uplink carrier corresponding to that bit is activated; if any bit in the fourth bitmap has a value other than the first value, such as the second value, it indicates that the uplink carrier corresponding to that bit is not activated.

[0168] Optionally, the first value can be 0 or 1. This embodiment of the disclosure is described with the first value being 1 and the second value being 0 as an example.

[0169] In another example, the MAC CE carrying the indication information may include:

[0170] The fifth bit map: each bit in the fifth bit map corresponds to one of the multiple serving cells of the terminal. If the bit value of one or more bits in the fifth bit map is the first value, it means that the serving cell corresponding to the one or more bits is activated; if the bit value of any bit in the fifth bit map is not the first value but is the second value, it means that the serving cell corresponding to the bit is not activated.

[0171] The sixth bit diagram: each bit in the sixth bit diagram corresponds to one uplink carrier among the multiple uplink carriers of the activated serving cell. If the bit value of one or more bits in the sixth bit diagram is the first value, it means that the uplink carrier corresponding to that bit in the activated serving cell is activated. If the bit value of any bit in the sixth bit diagram is not the first value but is the second value, it means that the uplink carrier corresponding to that bit in the activated serving cell is not activated.

[0172] Optionally, the first value is 1 and the second value is 0.

[0173] In step S2103, terminal 101 sends MAC CE to network device 102.

[0174] In some embodiments, network device 102 receives MAC CE.

[0175] In some embodiments, in this step, the MAC CE sent by terminal 101 to network device 102 includes at least one uplink carrier PHR.

[0176] Optionally, the MAC CE is used to send PHR and may be referred to as PHR MAC CE.

[0177] In some embodiments, the terminal can send at least one uplink carrier PHR to the network device through the MAC CE, thereby realizing PHR reporting per carrier.

[0178] In some embodiments, step S2103 may be performed when at least one uplink carrier satisfies a first condition, such as when the first condition is met, terminal 101 sends a PHR MAC CE to network device 102.

[0179] In some embodiments, the first condition includes at least one of the following:

[0180] At least one uplink carrier is an active carrier;

[0181] At least one uplink carrier active BWP is not a dormant BWP;

[0182] At least one uplink carrier's active BWP is switched from a dormant BWP to a non-dormant BWP.

[0183] Optionally, the active BWP of at least one uplink carrier is not a dormant BWP, including: the initial active BWP of at least one uplink carrier is not a dormant BWP.

[0184] Optionally, whether the carrier is activated or the activation method can be found in the description of step S2102.

[0185] Optionally, when any one or more of the above conditions are met, terminal 101 sends PHR MAC CE to network device 102.

[0186] In some embodiments, the PHR of at least one uplink carrier includes at least one of the following:

[0187] The PH corresponding to each uplink carrier in at least one uplink carrier;

[0188] The uplink transmit power corresponding to each uplink carrier in at least one uplink carrier;

[0189] Power back-off for each uplink carrier in at least one uplink carrier.

[0190] Optionally, for each uplink carrier, its PH can be determined based on the P of that uplink carrier. CMAX (The terminal determines this based on step S2201) or the network device determines the uplink transmit power configured for the uplink carrier in step S2101.

[0191] In one example, the PH index and the corresponding power headroom levels are shown in Table 1-1 below:

[0192] Table 1-1

[0193] Optionally, the power margin level can represent the power margin.

[0194] Optionally, the uplink transmit power refers to the power configured by the network device in step S2101, or the power determined by the terminal based on step S2201. CMAX .

[0195] In one example, the uplink transmit power (P) CMAX The index and corresponding nominal UE transmit power levels are shown in Table 1-2 below:

[0196] Table 1-2

[0197] Alternatively, the rated terminal transmit power level can also be referred to as the rated terminal transmit power.

[0198] Optionally, power back-off can be determined based on the Maximum Permissible Exposure (MPE). In one example, the Effective Power Reduction is shown in Table 1-3, with different MPEs and their corresponding Power-Max Power Reduction (P-MPR) values:

[0199] Table 1-3

[0200] In some embodiments, at least one uplink carrier is included in a plurality of uplink carriers in a cell, wherein the MAC CE, or PHR MAC CE, includes at least one of the following:

[0201] The first bitmap, in which one bit corresponds to one of the multiple uplink carriers in a cell, and at least one uplink carrier includes the carrier corresponding to the bit in the first bitmap with a bit value of the first value;

[0202] A neighborhood index for a residential community.

[0203] Optionally, in this embodiment, in the method of reporting PHR on a carrier-by-carrier basis, a single PHR MAC CE can be used to report the PHRs of different uplink carriers in a cell.

[0204] Optionally, a cell may be the primary serving cell Pcell of terminal 101, and the PHR MAC CE may be associated with a first LCID. Alternatively, a cell may be any serving cell of the terminal, and the PHR MAC CE may be associated with a second LCID. The LCID is used to identify the PHR MAC CE corresponding to any serving cell.

[0205] Optionally, the first LCID and the second LCID are different to distinguish between the two PHR MAC CEs.

[0206] Optionally, if a cell is the primary serving cell of terminal 101, then in the PHR MAC CE, the first bit map indicates whether the MAC CE includes the PHR of each uplink carrier in the Pcell. In this case, the cell is assumed to be the Pcell, and the MAC CE does not need to indicate the Pcell index through a separate field.

[0207] Optionally, if a cell is any serving cell of terminal 101, then in the PHRMAC CE, the cell index field indicates the serving cell index, and the first bit map indicates whether the MAC CE includes the PHR of each uplink carrier in the serving cell.

[0208] Optionally, the low-order bits to the high-order bits in the first bit diagram correspond one-to-one with the indices of multiple uplink carriers in a cell from smallest to largest; or, the low-order bits to the high-order bits in the first bit diagram correspond one-to-one with the indices of multiple uplink carriers in a cell from largest to smallest; or, the bits in the first bit diagram and the multiple uplink carriers correspond one-to-one in other ways.

[0209] Optionally, the first value indicates presence, and other values, such as the second value, that differ from the first value indicate absence. For example, in this PHR MAC CE, the PHR includes the uplink carrier corresponding to the bit with the first value.

[0210] For example, the first value is 1 and the second value is 0. If the bit value corresponding to an uplink carrier in the first bit diagram is 1, it indicates that the PHR MAC CE contains the PHR corresponding to that uplink carrier; if the bit value corresponding to an uplink carrier in the first bit diagram is 0, it indicates that the PHR MAC CE does not include the PHR corresponding to that uplink carrier, that is, this PHR MAC CE did not report the PHR for that uplink carrier.

[0211] In one example, a cell's PHR MAC CE is used for the PCell, and this PHR MAC CE is identified based on the associated first LCID. The PHR MAC CE includes a first bitmap corresponding to all uplink carriers of the PCell. Each bit in this first bitmap corresponds to one uplink carrier of the PCell. A bit value corresponding to a certain uplink carrier having a first value (e.g., a first value of 1) indicates the presence of a PHR report for that uplink carrier, while a bit value not corresponding to a certain uplink carrier having no PHR report. Furthermore, the low-order bits to high-order bits in the first bitmap correspond one-to-one with the indices of multiple uplink carriers in the cell, from smallest to largest. For example, referring to the schematic diagram of the MAC CE shown in Figure 2C, this PHR MAC CE is used for the PCell and includes:

[0212] The first bit map, in which UC0-UC7 can correspond to the 8 uplink carriers in PCell;

[0213] The P field indicates whether to report P-MPR measurements; the R field represents reserved bits.

[0214] PH (Type X, Primary Serving Cell, Uplink Carrier y) represents the power margin corresponding to Type X, Primary Serving Cell (Pcell), and Uplink Carrier y (UL carrier y);

[0215] The MPE field, if an MPE report is configured and the P field is set to 1, indicates the power back-off that meets the MPE requirements, and the MPE field indicates the index of the measured P-MPR value; if an MPE report is not configured and / or the P field is set to 0, the MPE field is replaced with the R field.

[0216] P CMAX,f,c P CMAX,f,c Uplink is used to indicate the P of the corresponding uplink carrier. CMAX (The terminal determines the uplink transmit power based on step S2201) or the network device configures the uplink transmit power for the uplink carrier in step S2101.

[0217] In one example, a cell's PHR MAC CE is used for any serving cell, and this PHR MAC CE is identified based on the associated second LCID. The PHR MAC CE includes the serving cell index of the serving cell, and also includes a first bit map corresponding to all uplink carriers of the serving cell. Each bit in the first bit map corresponds to one UL carrier. A bit value corresponding to a certain uplink carrier having a first value (e.g., a first value of 1) indicates that a PHR report exists for that uplink carrier, and a bit value not corresponding to the first value (e.g., a bit value of 0) indicates that a PHR report does not exist for that uplink carrier. Furthermore, the low-order bits to high-order bits in the first bit map correspond one-to-one with the indices of multiple uplink carriers in the cell, from smallest to largest. For example, referring to the schematic diagram of the MAC CE shown in Figure 2D, this PHR MAC CE is used for any serving cell. The main difference between it and the MAC CE shown in Figure 2C is that the MAC CE shown in Figure 2D includes a separate serving cell index field. The rest of the structure can be found in the description of Figure 2C. For example, UC0-UC7 in the first bit diagram correspond to the eight uplink carriers of the serving cell, which will not be described in detail here.

[0218] In some embodiments, at least one uplink carrier belongs to multiple serving cells of terminal 101, wherein the MAC CE, i.e., PHR MAC CE, includes at least one of the following:

[0219] The second bit map, in which one bit in the second bit map corresponds to one serving cell in different serving cells, and multiple serving cells include the serving cell corresponding to the bit in the second bit map whose bit value is the first value;

[0220] The third bit map is provided, where one of the multiple serving cells corresponds to one third bit map. One bit in the third bit map corresponds to one of the multiple uplink carriers in the corresponding serving cell. At least one uplink carrier includes the carrier corresponding to the first value bit in the third bit map of the multiple serving cells.

[0221] Optionally, in this embodiment, in the method of reporting PHR on a carrier-by-carrier basis, a single PHR MAC CE can be used to report the PHRs of different uplink carriers in multiple cells.

[0222] Optionally, the MAC CE is associated with a third LCID.

[0223] Optionally, the third LCID is different from the first LCID and the second LCID described above.

[0224] Optionally, the low-order bits to the high-order bits in the second bit diagram correspond one-to-one with the indices of the multiple serving cells from smallest to largest; or, the low-order bits to the high-order bits in the second bit diagram correspond one-to-one with the indices of the multiple serving cells from largest to smallest; or, the bits in the second bit diagram correspond one-to-one with the multiple serving cells in other ways.

[0225] Optionally, the low-order bits to the high-order bits in the third bit diagram correspond one-to-one with the indices of multiple uplink carriers of a serving cell from smallest to largest; or, the low-order bits to the high-order bits in the third bit diagram correspond one-to-one with the indices of multiple uplink carriers of a serving cell from largest to smallest; or, the bits in the third bit diagram correspond one-to-one with multiple uplink carriers of a serving cell in other ways.

[0226] For example, the first value is 1, and other values ​​different from the first value, such as the second value, are 0. If the bit value corresponding to a serving cell in the second bit diagram is 1, it means that the PHR MAC CE includes the PHR corresponding to the uplink carrier in that serving cell. If the bit value corresponding to a serving cell in the second bit diagram is 0, it means that the PHR MAC CE does not include the PHR corresponding to the uplink carrier in that serving cell.

[0227] For the serving cell corresponding to the first value in the second bit map, the uplink carrier corresponding to the bit value of 1 in the third bit map of the serving cell is further determined. That is, the PHR of the uplink carrier corresponding to the bit value of 1 in the third bit map is included in the PHR MAC CE. If the bit value of an uplink carrier of the serving cell in the third bit map of the serving cell is 0, it means that the PHR MAC CE does not contain the PHR of the uplink carrier.

[0228] In one example, if multiple cells report PHRs, meaning the PHR MAC CE includes PHRs corresponding to multiple serving cells, the PHR MAC CE is identified based on the associated third LCID. In this example, the PHR MAC CE may include a second bitmap of multiple serving cells, where the low-order bits to high-order bits of the second bitmap correspond one-to-one with the serving cell indices of the multiple serving cells from low to high. A bit value corresponding to a serving cell with a first value (e.g., a first value of 1) indicates that a PHR report for that serving cell exists, and a bit value corresponding to a serving cell that is not the first value (e.g., a bit value of 0) indicates that a PHR report for that serving cell does not exist.

[0229] If the serving cell's corresponding bit indicates the presence of a PHR report for that serving cell, then for that serving cell: a third bit map containing all uplink carriers of that serving cell is also included. Each bit in the third bit map corresponds to one UL carrier of that serving cell. A bit value corresponding to a particular uplink carrier having a first value (e.g., a first value of 1) indicates the presence of a PHR report for that uplink carrier; a bit value not having a first value (e.g., a bit value of 0) indicates the absence of a PHR report for that uplink carrier. Furthermore, the low-order bits to high-order bits in the third bit map correspond one-to-one with the indices of multiple uplink carriers in the cell, from smallest to largest.

[0230] For example, referring to the schematic diagram of MAC CE shown in Figure 2E, PHR MAC CE is used for multiple serving cells. PHR MAC CE includes a second bit map, in which C1-C7 can correspond to 7 serving cells; the serving cell corresponding to the first value bit in the second bit map can also correspond to a third bit map in this PHR MAC CE, in which UC0-UC7 can correspond to the 8 uplink carriers of the serving cell; the meanings of the remaining fields in Figure 2E can be referred to the descriptions in Figures 2C and 2D above, and will not be repeated here.

[0231] In step S2104, network device 102 sends power indication information to terminal 101.

[0232] In some embodiments, terminal 101 receives power indication information.

[0233] In some embodiments, power indication information can be used to indicate the transmission power information of the terminal 101 simultaneously uplinking on multiple uplink carriers.

[0234] In some embodiments, network device 102 may determine power indication information based on the PHR reported by the terminal based on PHR MAC CE.

[0235] In step S2105, terminal 101 reduces the transmit power of the first carrier and / or the second carrier according to the priority information corresponding to the first carrier and the priority information corresponding to the second carrier.

[0236] In some embodiments, this step may be performed when the sum of the transmit powers of simultaneous uplink transmissions on the first carrier and the second carrier is greater than a threshold.

[0237] Optionally, the transmit power for simultaneous uplink transmission on the first carrier and the second carrier can be determined based on the uplink transmit power configured by the network device in step S2101.

[0238] Optionally, the transmit power for simultaneous uplink transmission on the first carrier and the second carrier may be the transmit power indicated by the network device in step S2104.

[0239] In some embodiments, terminal 101 supports simultaneous uplink transmission on multiple uplink carriers in a cell, wherein the multiple uplink carriers include a first carrier and a second carrier. That is, the first carrier and the second carrier represent any two uplink carriers among the multiple uplink carriers.

[0240] Optionally, the threshold is the maximum transmit power of terminal 101; or, the threshold is a preset value, which is less than or equal to the maximum transmit power of terminal 101.

[0241] Optionally, the priority information corresponding to the first carrier and the priority information corresponding to the second carrier are used to indicate the order in which the first carrier and the second carrier reduce their transmit power.

[0242] Optionally, the priority information corresponding to the first carrier and the priority information corresponding to the second carrier are used to indicate the compression ratio of the first carrier and the second carrier in reducing the transmit power. The compression ratio can represent the ratio that can be satisfied when the transmit power of the first carrier and the second carrier is reduced.

[0243] In some embodiments, priority information and / or compression ratio corresponding to each uplink carrier are determined based on the physical channel type, transmission content, and / or uplink carrier of each uplink carrier.

[0244] Optionally, priority information and / or compression ratio corresponding to each uplink carrier are determined based on the physical channel type of each uplink carrier, the LCID corresponding to the transmitted content, the priority of the logical channel group (LCG) corresponding to the transmitted content, and / or the uplink carrier.

[0245] In another embodiment, terminal 101 may reduce the uplink transmit power of the first carrier and / or the second carrier based on the priority and / or compression ratio of the first carrier and the priority and / or compression ratio of the second carrier.

[0246] In one example, if the priority information corresponding to the first carrier is higher than the priority information corresponding to the second carrier, the transmit power of the second carrier can be reduced first. If the sum of the transmit power of the first carrier and the second carrier simultaneously transmitted uplink after the transmit power is reduced is less than or equal to the threshold, the uplink transmit power of the first carrier can be further reduced. If the sum of the transmit power of the first carrier and the second carrier simultaneously transmitted uplink after the transmit power is reduced is still greater than or equal to the threshold, the uplink transmit power of the first carrier is reduced again.

[0247] In some embodiments, terminal 101 reduces the uplink transmit power of the first carrier and / or the second carrier based on priority information corresponding to the first carrier and priority information corresponding to the second carrier, and / or compression ratio corresponding to the first carrier and compression ratio corresponding to the second carrier. The compression ratio characterizes the degree to which the uplink transmit power needs to be reduced. The compression ratio corresponding to the first carrier and the compression ratio corresponding to the second carrier can be the same or different. For example, the compression ratios can be related to their corresponding priority information.

[0248] It should be noted that the above implementation is only illustrated using the first and second carriers among multiple uplink carriers as an example. In another embodiment, for at least two uplink carriers among multiple uplink carriers, when the sum of the uplink transmit power transmitted simultaneously on the at least two uplink carriers is greater than a threshold, the terminal 101 reduces the uplink transmit power of at least one uplink carrier among the at least two uplink carriers according to the priority information corresponding to each uplink carrier among the at least two uplink carriers.

[0330] In the method provided in this disclosure, when a terminal reports a PHR to a network device, it sends the PHR of at least one uplink carrier, that is, it reports the PHR at the granularity of each carrier, which can reflect the PHR status of each carrier, thereby better assisting the network device in scheduling. To facilitate understanding of the embodiments of this disclosure, some examples are listed below:

[0331] Example 1: Determining the uplink transmit power corresponding to each uplink carrier

[0332] The uplink transmit power corresponding to each uplink carrier among multiple uplink carriers in a cell can be determined in the manner shown in either Option 1 or Option 2 below:

[0333] Option 1: Configure the network device with the maximum uplink transmit power for each uplink carrier.

[0334] Optional Example 2: The maximum uplink transmit power for each uplink carrier is determined according to the method for determining the maximum uplink transmit power for each SCell in the CA. For example, the terminal is allowed to set its configured maximum output power P for the uplink carrier f of cell c in each time slot. CMAX,f,c The maximum output power P is configured CMAX,f,c Set within the following range: P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c ;P CMAX_L,f,c =MIN{P EMAX,c –ΔT C,c ,(P PowerClass –ΔP PowerClass +ΔP PowerBoost )–MAX(MAX(MPR c +ΔMPR c A-MPR c )+ΔT IB,c +ΔT C,c +ΔT RxSRS P-MPR c )};P CMAX_H,f,c =MIN{P EMAX,c ,PPowerClass –ΔP PowerClass +ΔP PowerBoost}

[0335] Among them, P CMAX,f,c P is the maximum uplink transmit power of the uplink carrier. CMAX_L,f,c For P CMAX,f,c The lower limit value, P CMAX_H,f,c For P CMAX,f,c The upper limit of P EMAX,c P is the maximum permissible transmit power for the cell indicated by network device 102. PowerClass ΔP is the rated maximum power of terminal 101 in the corresponding transmission frequency band. PowerClass For the set additional power difference, ΔP PowerBoost For the set increaseable transmit power, MPR c For maximum power back-off, ΔMPR c A-MPR is the relaxation value for additional maximum power back-off. c To add maximum power back-off, ΔT IB,c Power relaxation due to multi-band operation, ΔT C,c For power relaxation at the frequency band edge, ΔT RxSRS P-MPR is used for power relaxation caused by antenna switching. c Maximum power reduction for human safety.

[0336] Optionally, P CMAX,f,c Equivalent to P in the above embodiments CMAX .

[0337] Optionally, the maximum uplink transmit power of the uplink carrier is equivalent to the uplink transmit power corresponding to the uplink carrier in the above embodiments.

[0338] Optional Example 3: Based on Optional Example 2 above, if the uplink transmit power of at least two uplink carriers simultaneously transmitting uplink is greater than the maximum transmit power of the terminal, then the uplink transmit power of each of the at least two uplink carriers needs to be compressed. The compression order is determined according to priority, and this priority and / or compression ratio can be determined according to the physical channel type, or the transmission content (e.g., the priority of the LCID or LCG corresponding to the transmission content), or different carriers.

[0339] Optionally, the terminal's maximum transmit power is equivalent to the threshold in the above embodiments.

[0340] Optionally, the priority is equivalent to the priority information in the above embodiments.

[0341] In some embodiments, the maximum uplink transmit power of each uplink carrier determined using the above-described optional example 1, optional example 2, or optional example 3 is used for the PCMAX of each uplink carrier in the PHR reporting.

[0342] Example 2: per carrier PHR (determining the PHR for each uplink carrier)

[0343] In some embodiments, PHR reporting can be done at the cell level or at the cell level.

[0344] Optionally, if reporting is done at the cell level, a cell can be a PCcell or any serving cell.

[0345] Optional Example 1: A cell's PHR MAC CE is used only for the PCell. The MAC CE is identified based on an associated LCID. The MAC CE contains a bitmap of all uplink carriers for the PCell. Each bit in the uplink carrier bitmap corresponds to an uplink carrier. Setting the corresponding bit to 1 indicates that a PHR report exists for that uplink carrier; otherwise, it does not exist. The low-order bits to high-order bits in the bitmap correspond one-to-one with the cell carrier index in ascending order.

[0346] Optional Example 2: A PHR MAC CE for a single cell is used for any serving cell. The MAC CE is identified based on an associated LCID. The MAC CE contains the serving cell index of the target serving cell and a bitmap of all uplink carriers for that serving cell. Each bit in the uplink carrier bitmap corresponds to an uplink carrier; a bit set to 1 indicates the presence of a PHR report for that uplink carrier, otherwise it does not. The low-order bits to high-order bits in the bitmap correspond one-to-one with the cell carrier index in ascending order.

[0347] Optional Example 3: If multiple cells report PHRs, meaning the MAC CE contains PHRs for multiple serving cells, the MAC CE is identified based on an associated LCID. The MAC CE contains a bitmap of the serving cells, where the low-order bits to high-order bits and the serving cell index correspond one-to-one. A corresponding bit set to 1 indicates the presence of a PHR report for that serving cell; otherwise, it does not. If the corresponding bit of a serving cell indicates the presence of a PHR report for that serving cell, then for that serving cell:

[0348] It also includes a bitmap of all uplink carriers for the serving cell. Each bit in the uplink carrier bitmap corresponds to a UL carrier. Setting the corresponding bit to 1 indicates that a PHR report for that carrier exists; otherwise, it does not. In the uplink carrier bitmap, the low-order bits to the high-order bits correspond one-to-one with the cell carrier index in ascending order.

[0349] Optional Example 4: Based on Optional Example 1, Optional Example 2 and Optional Example 3 above, the PHR report of each uplink carrier shall at least include the PHR value and the uplink transmit power, and optionally the PHR report of each uplink carrier shall include power back-off indication, etc.

[0350] Optionally, the PHR value corresponds to the power margin in the above embodiments.

[0351] Optionally, the power back-off indication is equivalent to the power back-off in the above embodiments.

[0352] Example 3: PHR Reporting Trigger

[0353] Optional Example 1: If the uplink carrier can be activated and deactivated, then if the uplink carrier of a serving cell is activated (being activated means that uplink transmission can be performed), and the initially activated BWP is not a dormant BWP, or if the uplink carrier's BWP is switched from a dormant BWP to a non-dormant BWP, then a PHR report is triggered.

[0354] Optional Example 2: For uplink carrier activation and deactivation, activation or deactivation of the uplink carrier of a serving cell can be based on the MAC CE. The MAC CE may include:

[0355] Case 1: Serving cell ID and the bitmap of the uplink carrier of the serving cell. Each bit in the uplink carrier bitmap corresponds one-to-one with a UL carrier. The corresponding bit is set to 0 to indicate deactivation and 1 to indicate activation.

[0356] Scenario 2: Bitmaps for all serving cells and bitmaps for the uplink carrier of each serving cell. In the serving cell bitmap, each bit corresponds one-to-one with a serving cell; a bit set to 0 indicates cell deactivation, and 1 indicates cell activation. The uplink carrier bitmap for the corresponding cell is only carried when the cell is active. In the uplink carrier bitmap, each bit corresponds one-to-one with an uplink carrier; a bit set to 0 indicates uplink carrier deactivation, and 1 indicates uplink carrier activation.

[0357] In this embodiment of the disclosure, a cell includes multiple carriers, and the terminal supports uplink transmission on multiple uplink carriers in a cell at the same time. In this case, when the terminal reports a PHR to the network device, it sends the PHR of at least one uplink carrier, that is, it reports the PHR at the granularity of each carrier, which can reflect the PHR status of each carrier, thereby better assisting the network device in scheduling.

[0358] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0359] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0360] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
